afforfleu Patented Jan. 11 1938 ANTIRATTLER. DEVICE FOR wmnows AND Elio V. Francescon, Boston, Mass. Application March 11, 1937, Serial No. 131,426 scams. (01. 292-76) This invention relates to a device to prevent rattling or involuntary motion of windows and thelike. h i

I am' well aware thatanti-rattler devices for this-purpose have been made by others, and it is one object of my invention to provide a superior device of this type, which is always reliable when once fixed in position for use. Other devices slip sidewise and ultimately fall out of their place between the window sash and the window jamb because of this side-slippage, and it has been a particular object to provide a device that overcomes this fault. Another object is to make a device together with means to fasten it in place at both ends, in a single unit from an integral piece of material. Recognizing that such devices must be sold for a small sum it has been my object to create one of such simple construction that it can be economically produced on a quanit) tity production basis, and, therefore, meet the price competition of inferior devices of this type and can be placed in position for use between the windowsash and jamb by one simple and obvious operation.

:5 The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction and arrangement of parts such as is disclosed by the drawing and specification. The nature of 30 the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to said disclosure; but am entitled to all such changes therefrom as fall Within the scope of my claims.

35- In the drawing:

Figure 1 is a front elevational view showing my device, by dotted lines, in its position between a window sash and a window jamb viewed from inside a house or building, in which position it 40 will prevent rattling or involuntary motion of the window.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a perspective view of my anti-rattler 45 device.

Figure 4 is a sectional view of an end portion of my device taken on the line 4-4 of Figure 3.

Figure 5 is a sectional view of my device taken on the line 5--5 of Figure 3.

50 Figure 6 is a bottom view of my device, broken away, showing an end portion viewed from the under side.

I have illustrated a portion of a window pane I2, set in a window sash I3 which has a front or 66 inner face 14 as viewed from inside a room where the window is. The window jamb or frame iii in which the window is movably mounted and which embodies the usual retaining strip, has an inner face i6 which is adjacent said inner face ll. Between said window sash i3 and said window 5 jamb l5 my anti-rattler device I! is mounted, preferably clinging to the said front face ll of said window sash l3 and bearing against the inner face l6 of the window jamb i5, whereby it serves as a. filler in the space between the said 10 window jamb and window sash, and prevents any rattling movement of said window sash.

As will be noted from Figure 1 of the drawing said device I! isso relatively small that it is out of sight when in position, being obscured from 15 view by said window jamb I5. The mounting of my device ll could be reversed, of course. to have it cling to the said window iamb inner face l6.

Said anti-rattler device is made in one piece, preferably of metal spring material, consisting of a main body portion l8 which protrudes or bows outwardly thereby resiliently bearing against said window jamb inner face l6, as shown in Figures 2 and 3 of the drawing. Said body portion 18 will yield or move sufiiciently to permit sliding of the window up or down; and it takes up the normal play space between the window sash and window jamb and thereby prevents rattling.

At each end of my device I! and integral therewith securing means are formed consisting of spurs IS on each side thereof, the material forming said device ll being turned downwardly and extending inwardly, as illustrated in the drawing, said spurs l9 being inset from the outside edges of my said device 11. Said spurs i9 penetrate into the wood of said window sash l3 and my device clings to its position thereon. It is a feature of my invention to form said spurs I9 so that they are inset from the ouslde edges of my device I1, thereby eliminating practically all possibility of having it fall from its position on said window sash by an outside comer thereof striking against said window jamb as the window is moved, which will occasionally happen if the said spurs I9 are not inset, as shown. To more permanently secure my devices I! in position I provide spur means 22 at the end which are preferably made double as shown, and which are located intermediate said spurs i9, being integral with said device 11. These intermediate spurs 22 likewise protrude into said window sash l3 and are so shaped that they slant diagonally downward from the said body portion l8 to the end as at 23, forming a sharp corner, as best illustrated in Figure 5 oi! the drawing. Inasmuch as a window will be slidup and down hundreds or thousands of times, said spurs 22 are an important feature of my invention, reinforcing, as they do, the grip of said outer spurs I9. Inasmuch as vertical movement of the window temporarily flattens out the body oi! my device I! somewhat, said spurs I9 and 22 move slightly in the paths they cut in the window sash l3 as the window moves; yet the spurs are so formed that they retain their grip on said windowsash and do not fall out despite this oftrepeated movement.

It is highly desirable to have said device I] remain indefinitely in position between said window sash Bidifiamb u, and in order to further attain this end I preferably provide said spu'rsl Band 22 in both ends of my device l1, although my invention is not necessarily limited to this particular construction. -v

Said side spurs is are purposely made longer than said intermediate spurs 22, to more surely overcome the effect of any sidev thrust; of said a window sash which otherwisemight tend to force my device out of its position What I claim is:

1. An anti rattler device for windows and the like comprising a bowed sheet spring with opposite edges at an end turned inward to provide spurs, and with a slit intermediate said spurs with portions adjacent to such slit turned inward to form other spurs, all said spurs cooperative to hold the device from displacement with respect to a window sash. J

2. An anti-rattler device for windows and the like comprising a bowed sheet spring with opposite side edges turned to project normally to said bowed sheet to provide spurs.

-3. An anti-rattler device for windows and the like comprising a spring body portion bowing outwardly, two spurs at each end thereof at the outer side edges extending downwardly and being inset from the outer side edges of said body portion, said spurs extending in a substantially straight line from the point of beginning at. said body portion to said ends, and two spurs at each 'saidend thereof at a point intermediate said spurs at said outer side edges spaced from each other and flaring outwardly from a common point 20 of beginning in said body portion towards said end,-saidspurs atsaid outer side edge beinglonger than said spurs at said intermediate point, and

of substantially the same depth throughout, the latter-mentioned spurs extending diagonally 25 downward towards said end and being of greatest depth at the end' of said device.
